Abstract: Alloying powder containing boron and carbon is melted into mild steel surface by argon arc, and the surface is alloyed. In this method, mild steel surface can be strengthened rapidly and expediently. The thickness of strengthened layer ranges between 2.5~4.0 mm. The inosculation between strengthened layer and matrix is metallurgic combination. In obtained strengthened layer, the primary fortifiers are Fe2B and Fe3(B,C), the hardness increases to 62~67 HRC, and both adhesive wear resistance and grit wear resistance are remarkably well.

Key words: Argon arc, Boron-carbon alloying, Mild steel
